Application May 3, 1946, Serial No. 667,164

3 Claims. (Cl. -575) The present invention relates to a louvered awning, and is particularly concerned with the provision of an extremely Simple and inexpensive structure of the class described, particularly adapted to be made of metal or other stiff but workable sheet material. The primary object of the invention is to provide a structure having the characteristics above-described which shall be relatively light, readily assemblable in any desired length and width, adapted to be hung for swinging movement about a horizontal axis at the top of a window frame, and adapted for ready and inexpensive repair or replacement of individual parts. A further object of the invention is to provide, for use with a device of the character described, simple but effective means for adjusting the position of the structure about its hinged axis. Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, my invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific construction illustrated and described, so long as the scope of the appended claims is not violated.

Fig. 1 is a front elevation of an awning constructed in accordance with my invention and associated with a window frame;

Fig 2 is an end elevation thereof;

Fig. 3 is an enlarged fragmental elevation of the upper portion of an awning constructed in accordance with my invention, and showing a fragmental section of the supporting wall therefor;

Fig. 4 is a broken perspective view of a fragment of my awning; and

Fig. 5 is an enlarged horizontal section showing a detail.

Referring more particularly to the drawings, it will be seen that I have illustrated an awning, indicated generally by the reference numeral I, supported in association with a window frame I I. A preferred form of support for my awning comprises a pair of hooks l2 secured to, and projecting from the window frame II in a common horizontal plane, each of said hooks being formed with a mouth l3 which opens upwardly and inwardly toward the supporting frame I I.

A pair of bars 14 and I5 are preferably connected, at their upper ends, by'a stretcher bar l8 which is adapted to be received in the hooks l2 to provide a hinged mounting about which the awning may swing.

The bars l4 and I5 are identical, but allochirally arranged; and therefore only one such bar is illustrated in detail. As is clearly shown in Fig. 4, the bar I4 is of channel construction, comprising a web I! flanked by flanges l8 and i9.

Upon the bar I4 is mounted a series of brackets, indicated generally by the reference numeral 28. Each bracket comprises an integral piece of sheet metal, of comparable stiff but workable sheet material. One straight edge portion of the bracket is turned, substantially at right angles out of the general plane of the bracket, as at 2|, and is then rebent upon itself, as at 22, to form a channel 23 opening toward the web l1. Another edge portion 24 of the sheet, disposed at an acute angle to the first-mentioned edge of the sheet, is likewise turned at right angles out of the general plane of the sheet. A tongue 25 is punched out of the body sheet, in a region intermediate the two above-described edges, and turned substantially at right angles out of the general plane of the sheet, and is then rebent upon itself, as at 26, to form a channel opening toward the web H. A further portion 28 of the sheet is cut loose from the sheet body, in a region below the tongue 25, leaving a connecting bar 21 between the edges 2| and 24, and said portion 28 is turned substantially at right angles out of the general plane of the sheet, into coplanar relation with the tongue 25. Said ortion 28 is then rebent upon itself, as at 28, to provide a channel opening toward the web I'I.

As will be readily perceived upon inspection of Fig. 4, the bracket 20 may be slidably positioned upon the bar l4, the channel 23 receiving the bar flange I8, and the channels formed by the tongue 25 and the portion 28 receiving the bar flange IS. The construction of the bracket is such that the edge 24 now lies in a plane acutely angularly related to the bar flange l9, and meeting said flange in a horizontal line.

Each bracket 28 on the bar l4 has an allochirally arranged mate upon the bar IS, the edge portion 24 of each bracket lying in a common plane with the corresponding portion of its mate upon the other bar. Extending between, and fixed to, such inclined edge portions of each pair of brackets is a slat 38 which may be formed of sheet metal or of any similar stiff but workable sheet material, each such slat preferably being formed, at its upper edge to provide an upwardly and forwardly turned flange 3|, and being formed at its lower edge to provide a downwardly turned flange 32. The flange 3| of each slat (save the uppermost slat) overlaps the lower portion of the immediately superjacent bracket, as is clearly to be seen from Fig. 3; and the flange 32 of each slat depends below the level of the upper edge of the flange 3| of the next subjacent slat.

A slat 30' is associated with the topmost brackets of the two bars; and it, too, is formed at its upper edge with an upwardly and forwardly turned flange 3|, and at its lower edge with a downturned flange 32'.

The hooks I2 are so positioned that, when the stretcher bar I6 is supported therein, the edge portions 2I of the brackets mounted on the bars I4 and I5 are spaced from the wall II a distance slightly greater than the horizontal distance between the bases of the hooks I2 and the mouths I3 thereof. Because of this arrangement the awning may be dismounted from the hooks by an upward and inward movement thereof, whereby the bar I6 is carried out through the mouths of the hooks, the bars I4 and I5 being thereby moved substantially into contact with the wall II.

Because of this necessary spacing of the bars I4 and I5 from the wall, the flange 3I' is preferably so arranged as to be moved substantially into contact with the wall II when the bottom of the awning is swung outwardly.

A bracket 33 is secured to the window frame II, at a point below the hooks I2, and provides a pivotal mounting for a lever 34. Said lever is provided, at its outer end, with a portion 35 located substantially in engagement with the web I! of the bar I4; and said lever carries a hook 36 adapted to embrace the flange I8 of said bar I4. Said hook projects through a suitable opening in the lever 34, and carries a wing nut 31, whereby said hook may be tightened into clamping engagement with the bar I4. Obviously, the parts are shown, in Fig. 2 with the lever 34 holding the lower end of the awning outwardly substantially to its limit of movement; and it will be clear that, upon loosening of the wing nut 31, the lever 34 may be swung in either direction about its pivotal mounting on the bracket 33 to adiust the angular position of the awning I 0 with respect to the window frame I claim as my invention:

1 A louvered awning comprising a pair of downwardly and away from its bar, said inclined portion of each bracket being coplanar with the corresponding portion of a mating bracket in the other series, and a slat extending between and secured to said inclined portion of each mating pair or brackets.

2. For use in an awning, a bracket comprising an integral sheet, one straight edge of said sheet being turned substantially at right angles out of the plane of said sheet, another edge 01 said sheet, inclined at an acute angle to said first-named edge, being turned substantially at right angles out of the plane of said sheet, and a portion of the body of said sheet intermediate said edges being turned substantially at right angles out of the plane of said sheet into substantial parallelism with said first-named turned edge, but leaving an integral bar joining said edges.

3. The bracket of claim 2 in which the substantially parallel turned portions are inwardly rebent upon themselves to provide substantially parallel channels opening toward the Plane of said sheet.
